QUESTION 46It is common to use Resilient Ethernet Protocol (REP) on the manufacturing floor as a resiliency protocol, as opposed to the Enterprise where it is not generally deployed. What are two reasons why REP is more suitable for the plant floor? (Choose two)

A. REP is only supported on Industrial Ethernet switches, it is not supported on Catalyst switches.B. REP converges faster than Spanning Tree, allowing for greater network availability.C. REP supports Industrial Ethernet protocols better because it moves the packets faster.D. Running dual cables from access switches to an aggregation switch can have a much higher cost on the plant floor than in the Enterprise and running a ring protocol like REP provides resiliency at a lower cost.E. Industrial protocols can be negatively impacted by the number of nodes the Ethernet frame traverses, REP provides a topology with no more than 3 nodes for any data path.

QUESTION 51Refer to the exhibit. You are required to implement traffic segmentation in the network. See the table for relevant device details:

L2SW4, L2SW5, and L2SW6 are connected to L3SW1 with 802.1Q trunks with VLAN 191 and VLAN 398 allowed on the trunk.You have the following information from L3SW1:L3SW1# show run interfacesinterface Vlan1no ip addressshutdown!interface Vlan2ip address 10.2.2.2 255.255.255.248!interface Vlan191ip address 10.10.27.126 255.255.255.192!interface Vlan200ip address 10.20.20.1 255.255.255.248!interface Vlan398ip address 10.15.153.1 255.255.255.0L3SW1# show ip route*** Output Omitted ***10.0.0.0/8 is variably subnetted, 5 subnets, 3 masksC 10.2.2.1/29 is directly connected, Vlan2C 10.10.27.64/26 is directly connected, Vlan191C 10.15.153.0/24 is directly connected, Vlan398C 10.20.20.0/29 is directly connected, Vlan200S 10.200.200.0/24 [1/0] via 10.20.20.2S* 0.0.0.0/0 [1/0] via 10.2.2.1You are required to implement a configuration that will meet the following connectivity requirements:– The Administrator’s Station must have full access to PanelView– PanelView should have limited access, based on specific TCP ports, to PLC#1 and I/O#1– The Administrator’s Station should have no access to PLC#1 and I/O#1– PLC#1 and I/O#1 should be able to communicate with each other on any portWhich action will allow you to meet the connectivity requirements?

A. Put interface VLAN 191 and interface VLAN 398 into different Virtual Routing and Forwarding (VRF) instances on L3SW1B. Deploy an inbound ACL on interface VLAN 191 to control the traffic from the Administrator’s Station and PanelView to PLC#1 and I/O#1C. No change is required, the traffic is already limited appropriately by the VLAN segmentationD. Implement an ACL on Firewall1 to control the traffic flow between VLAN 191 and VLAN

Answer: B

QUESTION 54ProfiNET has been disabled on a Cisco Industrial Ethernet switch. Which CLI command will correctly enable ProfiNET on the switch?

QUESTION 55Which describes a best practice rule for controlling traffic between the corporate network and the controls network?

A. Outbound traffic from the control network to the corporate network and outbound traffic from the corporate network to the control network can be restricted based on source and destination address only.B. Outbound traffic from the corporate network to the control network should be restricted but outbound traffic from the control network to the corporate network should not be restricted.C. Outbound traffic from the control network to the corporate network should be restricted based on source and destination address and service only.D. Outbound traffic from the control network to the corporate network should be restricted based on source and destination address, service, and port.

Answer: D

QUESTION 56Which statement is true regarding ProfiSAFE?

A. ProfiSAFE traffic must be carried on a network that is physically separated from automation trafficB. ProfiSAFE relies on the error detection mechanisms of Ethernet and TCP/IP to determine if there are network errorsC. ProfiSAFE can be used in safety applications up to Safety Integrity Level 3 (SIL3)D. ProfiSAFE is only used by ProfiBUS PA and ProfiBUS DA devices
